-10/1 is the correct answer
First restaurant price: 29 + 6l = x
x = final cost
l = kilo of lobster
Second restaurant price: 41 + 3l = x
We want them to be the same price, so: 29 + 6l = 41 + 3l
Subtract 3l from each side
29 + 3l = 41
Subtract 29 from both sides
3l = 12
Divide both sides by 3
l = 4
So, if she buys 4 kilograms of lobster from either place, it will cost the same.
It would cost $53.
Answer: x = 1.4
Step-by-step explanation:
Simplify:
6-5x+1 = 0
Subtract 1 from both sides:
6 -5x = -1
Subtract 6 from both sides:
-5x = -7
Divide both sides by -5:
x = 1.4
